UPDATE 2/28/2017 1:56 PM. Received the replacement cam sensor cup and installed in about 5 minutes. Took a little bit of cranking but it fired off. The idle was high and reset to about 950 RPM. Waiting for replacement cam cover so duct taped to keep dirt out. Road around for about 30 minutes varying speed up to 45 MPH. response seems good.

ISSUE: Sounds like rocks bouncing around in the fuel tank when I go a little heavy on the throttle. Kind of like a variable screaching noise. Its real noticeable. Kind of comes and goes and if I'm lite on the throttle it minor to gone. Everything is tight gas tank, fittings etc. Noise does not happen sitting still and revving the engine.

#1-I have read that the carb to intake manifold has to be property seated/sealed and I "think" it is. I used new intake manifold seals putting it together.

#2- I used a support bracket to hold the carb & air filter on. It connects to each inner head and now part of the head vent assembly. The vent head assembly has the (2) 3/4" hollow bolts that collect into common tube that sits above the carb. I had to pack out the bracket with a couple washers on each of the bolt heads so it would face up to the Mukuni throttle opening.

Short of the noted noise when riding the engine sounds normal.

Thoughts appreciated.

 

If what your talking about in the tank sounds similar to marbles I would suggest you retard the timing a little... Or get a light and set it properly by the book. Or you can turn your ignition plate a little clockwise and take it for another ride to see if it stopped. You might have to do that more than once....

 

UPDATE: 2/28/2017 3:03 PM.

I just went out and noticed that I didn't put the rubber hose on the vent/drain on the engine head vent near the carb. Rocks bouncing around is gone......

Took it up on the highway bypass and ran it up pretty good. Throttle nice and smooth & responsive.

I've gotten as far as I want to go with this and quite pleased with the success. I have a friend that owns a custom cycle shop and can now ride it over to have him go thru everything and make sure the carb and timing is dialed in right etc..I didn't want to give up trying to get it running and trailer the bike over.....

I want to thank everyone's comments/help to getting me to the finish line. GREAT FORUM and couldn't have done this with out your help.

Later I'll posted what parts I used and what I did on this conversion.

Big relief getting the MM fuel injection system off this bike to something like a basic carb.

Again, thanks all!!

 

I'm glad you got it all sorted out.

 

Glad you got it all sorted out. Ride safe

 

All the EFI version has is the bank angle sensor on it that the others do not. It has adjustable slots for non EFI use or it has the two holes for EFI use.

The cup is the real difference and how you set the plate using slots instead of the holes for adjustment of timing.

Griz

 

Ride with pride... Well done.........

 

Thanks for the info!!!

I would love to see this parts list as I am about to begin my conversion. Since I not a DIY guy I'll be having a shop do the work but I do need some direction because not all the techs in the shop can have a conversation about these old machines.
Great topic, much appreciation.

 

Best to start your own new thread for your project, but here's the list some of us used.
